No requirements at all except don't be malignant towards the fleet and log in once in a while. We operate under the philosophy that forcing members to participate makes them unhappy and less likely to want to participate. We want you to play at your pace.

The forums here detail information on the fleet operations and allow for member feedback.

For the past several days I have had major issues logging in any time before 12/1 am my local. When I do get in it lags and jellies like never before. Now @ 12:57am I can't get in again and the server is down. WTH is going on @ craptic?
